Whakaahuatanga Hua
He matū whānui te polyurea e whakamahia ana, kua angitu te whakamahi hei ārai i te waikura o ngā mata o ngā tāke rokiroki, hei ārai wai i ngā hanganga raima pēnei i ngā papa waka, ngā puna wai, me ngā kauhanga, hei whakakī hononga, hei hiri rānei.
- He roa te rārangi o ngā rauemi ka taea te whakarārangi hei mea e whakamahia ana hei paninga ātete wai. Mō ngā rautau maha, ko ngā hua uku anake te mea i wātea. I te rautau 20, he maha atu ngā rauemi i whakawhanakehia, tae atu ki te epoxy me te vinyl ester.
- Ko te Polyurea te hangarau paninga hou rawa atu. I whakawhanakehia tēnei rauemi mō te umanga motuka i te mutunga o te tekau tau atu i 1980, ā, e whakamahia whānuitia ana i roto i ngā momo mara. Nā tōna tere o te whakamaroke, tōna ātete ki te waikura, me tōna ātete ki te kakahu, kua nui te ahunga whakamua i roto i te hangarau ārai wai i ngā tau 10 kua pahure ake nei.
- I te wā i hangaia ai te polyurea, i tumanakohia kia whai rauemi polyurethane kāore e tino pāngia e te wai. Mā te whakakapi i ngā rōpū carboxyl i roto i te polyurethane ki ngā rōpū amino, i puta mai te hua e kiia nei e tātou ko te polyurea. He iti ake te pāngia o tēnei hua e te wai i ērā atu paninga polyurethane.
- E rua ngā momo noa o te Polyurea. He maha ake te whakamahinga o te polyurea kakara. Ka rerekē te mahi ā-tinana o tēnei hua, ā, he maha ngā whakamahinga rerekē. Inaa, ko te ngoikoretanga anake o tēnei paninga ko te kore pumau o te UV. Ko tētahi atu momo ko te polyurea aliphatic. Mā te whakamahi i ngā tikanga matū rerekē hei whakapai ake i te pumau o te UV, ka utua he utu whiu. Ko te utu o tēnei polyurea he rua te nuinga o te wā i te polyurea kakara.
Ngā āhuatanga o te hua
He momo paninga hou o te polyurea, he maha ngā āhuatanga whakamiharo o ngā paninga polyurea.
- He tino pai ngā āhuatanga ā-tinana o tēnei mea, pērā i te ātete pai ki te kakahu, e āhei ai te paninga ki te pupuri i tōna āhua me tōna pānga tiaki mō te wā roa ahakoa i roto i ngā taiao e pāngia ana e te waku me te kakahu pinepine;
- I taua wā anō, he tino kaha tōna ātete ki ngā pānga, e ātete ana i ngā kaha pānga o waho, ā, e tiaki ana hoki i te mata o te mea kua pania mai i te kino.
- Mō ngā āhuatanga matū, he tino ātete ngā paninga polyurea ki te waikura. Ahakoa e pāngia ana e te mimiti o ngā waikawa, te kawakore, te taiao matū kino rānei pērā i te haumākū nui me te rehu tote nui, ka taea e rātou te noho pumau mō te wā roa, ā, kāore e ngāwari ki ngā tauhohenga matū e kino ai te paninga.
- Heoi anō, he pai tōna ātete ki te huarere, e mau tonu ana tōna pumau i roto i ngā āhuarangi rerekē, pērā i te pāmahana teitei, te pāmahana iti, me te hihi ultraviolet, me te kore e pāngia e ngā raruraru pērā i te paura, te rerekētanga o te tae, te kiri rānei nā ngā huringa āhuarangi. He tino tere te tere o te whakamaroke o ngā paninga polyurea, e whakapai ake ana i te whai huatanga o te hanga, ā, ka taea te whakaoti me te whakamahi i te paninga i roto i te wā poto.
- Heoi anō, he pai te piri ki ngā momo papa, ka taea te piri pūmau ki ngā mata o ngā mea whakarewa, raima, rakau, me ētahi atu, ka hanga he paparanga tiaki pakari, pumau hoki.
NGĀ PAINGA O TE HUA
- Ko tētahi o ngā take i tere ai te rongonui o ngā paninga polyurea ko te whānuitanga o ngā āhuatanga pai kua whakaatuhia. E kī pūmau ana te paetukutuku Polyurea.com, mō ngā āhuatanga ā-tinana e wātea ana, kāore he paninga kē atu o te ao e taea te rite ki te polyurea. Mā te whakarerekē i te tauira, ka taea e ngā hua polyurea te whai i te whānuitanga o ngā āhuatanga, mai i te roanga teitei ki te kaha kume pai rawa atu, engari e pā ana tēnei ki te tauira o te rauemi me te tono tika. He pai te piri o te Polyurea ki ngā momo papa tae atu ki te raima, te konganuku, me te rakau, ahakoa kāore he paninga, ā, ka taea te whakamahi i roto i ngā taiao he whānui ngā rerekētanga pāmahana me te haumākū. Ko te painga tino whakamiharo o te polyurea ko tōna tere rawa o te whakamaroke. Kia pania, ka taea e te polyurea te tae ki te matotoru e hiahiatia ana i roto i te kotahi paninga, he maha ngā wā tere atu i te whakamahi i ngā paninga tuku iho, ka taea ai e te rangatira te whakamahi anō i te whare me te whakaiti i ngā ngaronga nā te wā kore mahi.
- Ko te matotoru o te paninga kotahi o ngā paninga polyurea ka rerekē mai i te 0.5mm ki te 12.7mm, ā, ko te wā whakapakeke ka rerekē mai i te wā tonu ki te 2 meneti pea, he mea e āwhina ana ki te tere o te tae ki te āhua e taea ai te whakamahi.
- Hei paninga kiriata matotoru e tere te whakamaroke, ina hiahiatia he ārai wai mō te kiriuhi, he pakari hoki, he pai te whiriwhiri i te polyurea. Ka taea hoki te whakatutuki i ētahi atu āhuatanga, pērā i te hiahia kia kore e paheke me te kakano o te mata, mā roto i ētahi tikanga. Ka taea te peita i te paninga, ā, ka taea hoki te whakamahi ki ngā wāhi e tutuki ana i ngā whakaritenga wai inu.
- Nā te whānuitanga o ngā āhuatanga mahi, he whānui rawa ngā whakamahinga o te polyurea. Ko te arai o roto o ngā tāke rokiroki, ngā paparanga tiaki tuarua, me te tiaki mata o ngā piriti ngā wā e whakamahia whānuitia ana mō tēnei momo rauemi. Inaa, he tata kore mutunga ngā mea ka taea te whakamahi i te polyurea.
- He maha ngā wā ka pāngia ngā tāke o ngā tipu maimoatanga waipara e te awhiowhio, te horoi, me te nui o te hau hauwai whanariki i te wā e tātarihia ana, e whakaranua ana, e whakamaroke ana hoki. Mā te whakamahi i te polyurea ka taea te whakarato i te ātete-kakahu, te ātete matū, me te ātete pānga e hiahiatia ana, ā, ka taea te whakahoki wawe i te wheketere ki te mahi, he tere ake i te maha atu o ngā tikanga.
- Ina whakamahia ki ngā piriti me ētahi atu wāhi e pāngia ana e te wiri me te nekenekehanga, ko te ngāwari o te polyurea tētahi atu painga i ērā paninga angiangi, kāore i te tino ngāwari pērā i te epoxy.
Ngā ngoikoretanga o te hua
- Heoi anō, he ngoikoretanga anō hoki tō te polyurea. He utu nui ngā taputapu e hiahiatia ana mō te paninga o te polyurea, mai i te $15,000 ki te $50,000, neke atu rānei. Ka eke pea te utu mō tētahi papa hangahanga pūkoro kua rite rawa ki ngā taputapu katoa ki te $100,000.
- He nui ake te utu o ngā rauemi polyurea i ērā atu paninga. He nui ake te utu tīmatanga i ērā o te epoxy. Heoi, nā te mea ko te roa o te ora o ngā paninga polyurea e 3 ki te 5 ngā wā i ērā atu hua, he pai tonu te whai hua o te utu i te wā roa o te ora.
- Pērā i ngā rauemi ārai wai katoa, ka taea hoki e te hanganga hē te arahi ki te korenga o te tono. Heoi, he tino teitei ngā whakaritenga mō te hanganga me ngā paninga polyurea. He mea tino nui te maimoatanga mata pēnei i te paninga onepu, te paninga tuatahi rānei mō te polyurea. Ko te nuinga o ngā kaupapa paninga polyurea i rahua kāore e pā ana ki te polyurea tonu, engari nā te maimoatanga mata hē, kino rānei.
Hanganga
- Ko te nuinga o ngā polyurea e whakamahia ana mō te ārai wai ka hangaia mā te whakamahi i ngā taputapu rehu maha-wāhanga. I te nuinga o te wā, ka whakamahia he pūnaha wāhanga-rua, ko te ranunga kapia amino me te rauemi isocyanate ka rongoatia motuhake ki roto i ngā ipu 50-karani. I te wā e hangaia ana i te papa mahi, ka whakawhitia ngā mea o roto i ngā ipu 50-karani ki te tāke o ngā taputapu rehu ka whakamahanatia ki te pāmahana e tika ana (60-71°C). Kātahi ka tukuna te isocyanate me te kapia polyol mā roto i te ngongo whakamahana ki te pū rehu.
- Ka tino whakahaerehia te ōwehenga o ngā matū e rua, he ōwehenga 1:1 te nuinga o te wā.
- Ka inehia te wā whakapakeke o te polyurea i roto i ngā hēkona, nō reira ka taea anake te whakaranu i ēnei matū i te wā tonu ka puta mai i te pū rehu; ki te kore, ka whakapakeke, ka mārō i roto i te pū rehu.
- Ka hoko ētahi kaihanga i ngā waeine rehu pūkoro katoa, tae atu ki ngā taputapu me ngā taputapu katoa, e tāutahia ana ki runga i ngā wakatō, i ngā moenga taraka rānei.
